Specification of Letters Patent.

Patented July 19, 1921.

Application filed May 16, 1916. Serial No. 97,819.

To all whom it may concern Be it known that I, JOSEPH A. Goon, a citizenof the United States, residin at Chicago, in the county of Cook and tateof Illinois, have invented certain new and useful Improvements inLiquid-Dispensers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothersskilled in the art to which it appertains to make anduse the same.g

This invention is a liquid dispensing de vice adapted more particularlyfor containand dispensing ink and similar fluid substances which areliable to readily evaporate and wherein it is desired to frequentlyobtain small quantities of the substance.

The object of the invention is to store a quantity of the fluid in areservoir or vessel which is substantially sealed against evaporationand the gathering of dust and dirt, and at the same time to provideareceiving receptacle or trough in which a small quantityofthe fluid maybe exposed for ready meet a predetermined level, the fluid beingpassedfrom the reservoir to the receiving receptacle or trough bymanually controlled devices. A further object of the invention is toprovide a valve whereby the fluid in the receiving receptacle or trou 11may be returned to the reservoir and t e reservoir thereafter sealed toprevent loss of the substance by evaporation. Substantially all of theoperable elements of the de vice may be included in one body, wherebythe cost of manufacture is materially reduced and the appearance andsalability of the device is increased. 1

he device is simple in construction, durable and eflicientlin operation,the return of the fluid to the reservoir from the receivingjreceptacleor trough operating to Wash the trough by the flushing action ofthefluid pumped back and forth through the duct connecting the reservoirwith the trough.

Other objects and features of novelty will become apparent from thefollowing detail description of the invention, taken in connection withthe accompanying drawings and the appended claim. i g

While preferred embodiments of the invention are disclosed. in. theaccompanying drawings, it is to be understood that the Y constructionstherein shown are for the puris indlcated at 1, and,

poses of illustration only, and not as definmg the limits of theinvention.

In the drawings Figure 1 is a plan view of an ink well, disclosing theinvention.

Fig. 2 is a sectional view on the line 2-2 of ig. 1.

Fig. 3. is a detail sectional view of another form of device disclosingthe rotatable valve positioned in the duct connectmg the reservoirwiththe discharge trough.

F g. 4 is a sectional view of another embodlment of the inventiondisclosing the top portion of the well and feed duct separate from thebase of the well.

The device is shown applied to an ordinary ink well for dispensing inkfrom the reservoir or well proper to a pen-dip trough, or reservoirsection, the well being provided with a resilient closure, which, whenoperated, acts upon the impounded air within the reservoir to ink andforce the ink from the reservoir through the duct to the pen-dip trough.The supply of ink in the trough may be limited to a predetermined heightby providing a break in the wall of the reservoir,

whereby the fluid in the pen-dip trough may flow back into the duct andreservoir when the levelof the fluid in the trough is higher than thatin the reservoir. Furthermore, the pen-dip trough may be washed by thefluid of the reservoir through means of a rotatable valve elementpositioned in the connecting duct and the manipulation of the resilientelement of the reservoir.

.Referring more particularly to the embodiments of the invention setforth in the accompanying drawings, the base or a stand provided with enracks Qand a recess 3. Thebase may e-formed of a single piece ofmaterial, such as glass,and provided with a' reservoir section in theform of a container indicated at 4, such reservoir section being shownprovided with a top 5 and bottom 6. The top 5 may be provided with afilling aperture 7, the wall of which terminates in an annular ring 8 toprovide a recess for the reception of an end of a resilient member 9.This resilient member may be of any desired form and material, and inpractice may be constructed in the form of a rubber cap, which is shownconcavo-convex' in form and provided with a press against the body of,

if desired, may be binding ring 10. The aperture 7 of the reservoir 4may be provided also with a plate 11 to limit the compressing movementof the resilient element 9. e

In the construction illustrated in Fig. 2, the base 1 is provided withan upstanding wall 12 which is broken intermediate its length and offsetasat 13 to form an upper section 12 of the wall with a passage 14between the sections 12 and 12. The top 5 of the reservoir is shownprovided with a depending wall 15 which extends from the top tosubstantially the base 6 of the reservoir, and forms a part of a'discharge duct 16for the reservoir. V

Positioned adjacent the reservoir and formed by a base wall 17 and aside wall 18 is the receiving receptacle, which may serve as a pen-diptrough, the receptacle being indicated at 19. The bottom17 of thisreceptacle is shown on a plane above that of the bottom 6 of thereservoir, and the aperture 14 between the'wall sections 12 and 12 maybe on a plane above that of the liquid level in the reservoir, suchliquid level being indicated by the line 20 in Fig. 2. 1

The upper endof the discharge duct 16 may be of greater'area than thatportion' of the duct which connects the reservoir with the receivingreceptacle 19, such enlarged portion being indicated at 21 in Fig,

2, and closed by a removable cap 22. Thls cap permits of the cleaning ofthe duct 16 and passage 14, should the flow of fluid from the reservoirto the receiving receptacle be impeded by the clogging of the ductbysediment due to evaporation of the fluid substance. I v

In the embodiment of the lnvention disclosed in Fig. 3, the wall 15 isshown ex tending to substantially the base 6 of the reservoir toformtheduct 16, but the wall 12 ofthe reservoir is not shown offset toprovide the end 12 as in Fig. -2. In the duct 16 there 'is shown arotatable valve element having a head 23 and a hollow stem 24, said stembeing provided with'a port 25 near the head 23 and another port 27 nearthe lower end of the tubular end and opposite to the port 25. Thewallindicated at 12 is pro vided with a lower .port 27 which leads from'thepen-dip trough19 to the duct 16, on a level with the bottom 17 of saidtrough, and said wall 12 is provided also with a port 28 which registerswith the upper port 25 of the rotatable valve 23.

When it is desired to supply ink to the pen-dip receptacle 19 andmaintain it in the receptacle, the valve 23 is rotated to the positionshown in Fig. 3 so that fluid from the reservoir may be forced, byoperating the cap 9, through the duct 16, the tube 24 and the ports 25,28 into the receptacle 19. When the operator is through using the welland desires to return the fluid to the reservoir, the valve 23 isrotated to the opposite position to that shown in Fig. 3 and so that theport 26 registers with the port 27,thereby permitting the fluid in thepen-dip trough 19 to flow from said trough throu h the duct 16 and backinto the reservoir. f it is desired to flush the pen-dip trough and washsaid trough of any sediment which may have occurred in said trough, thevalve 23 may remain in the latter position while the resilient element 9is depressed and raised slowly and successively to force fluid into thepen-dip trough 19 and permit it to flow out of the same until saidreservoir becomes substantially free from sediment. Thereafter, thevalve may be rotated a quarter turn to move its ports 25, 26 out ofregister with the ports 27, 28 and operate to substantially seal thereservoir against the ingress or egress of fluid. The reservoir may befilled by removing the cap 9, or in any other suitable manner.

Referring to the construction shown in Fig. 2, I may refer to constructa device as shown in F 1g. 4, wherein the base 1 is provided with thereservoir section 4 and the receiving receptacle 19 positioned adjacentthereto, as previously described. In this construction the wall of thereservoir 4 may be of the same thickness and is indicated at 29, exceptfor the front section of the wall which forms a part of the pen-dip 19which is indicated at 30. This section of the wall 30 is shown slightlylower than the rear section 29.

Cooperating with the base 1 is a removable cover section which isprovided with the usual top 5, having the annular ring 8 to receive aresilient or compressible member 9, as previously described. The top 5,however, is shown provided with a flange 31, designed to rest upon thewall 29 and a depending flange 32 to bear against a side wall 29, itbeing understood that said wall 29 extends from the back to, andincluding each side of the wall, if so desired. At the front part of thetop, there may be formed a depending flange 33 to rest against the faceof the wall 30, which is directed toward the pen-dip l9, and if desired,this section of the top may be provided also with an interior flange 34to rest against the opposite face of said wall 30. In the drawings thereis shown a passage 35, formed in the flange 33 and through the frontsection of the top, said passage leading from the reservoir 4 to thepen-dip 19. It is preferred to connect said passage 35 with the lowerportion or bottom face 6 of the reservoir 4, and to accomplish thispurpose, there may be provided a tube 36 which communicates with thepassage 35 and extends into closer proximity to the bottom wall 6 of thereservoir. By an inspection of Fig. 4, it will be understood that theeompression of the member 9 will act upon the impounded air in reservoir4 to force the fluid from said reservoir through the tube 36 and passage35 into the pen-dlp 19, as the fluid 1n the dip may be consumed.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent of the United States, is

A device of the class described, comprising a reservoir, and areceptacle, a su ply duct connecting the reservoir with-sai receptacleand provided with an inlet port leading to the top of the receptacle andan outlet port leading to the bottom of the receptacle, a single valvemounted in the duct 15 adapted to close both ports or open one at will,and means to cause the contents of the reservoir to flow into the recetacle.

In testimony whereof, I ai x my signature, in presence of two witnesses.
